Calculators and planners for every project.
No accounts, no email walls. Every tool saves its inputs to a shareable URL so you can come back, share with your contractor, or use the same numbers in the next tool.
Appliance Lifespan Tracker
Log your refrigerator, water heater, HVAC, and every other major appliance once, and see at a glance what's healthy, what's aging, and what's overdue for replacement — so you can budget ahead instead of scrambling when something fails.
Bid Comparison Tool
Compare 2 to 4 contractor quotes side by side. Enter each bid line by line and the tool lines them up on a shared table, flags the items a bid leaves out, marks price-spread outliers, and surfaces red flags like a high deposit or no warranty — so you can get every contractor quoting the same scope.
Closing Cost Estimator
The 2–5% of the purchase price that first-time buyers forget to save for, due at closing on top of the down payment. Break down lender fees, title and settlement, government charges, and prepaid escrow, and see the total cash you'll actually bring to the table.
Concrete Calculator
Cubic yards of ready-mix to order — or bags to buy — for slabs, patios, footings, and post holes. Enter the dimensions and quantity, add a waste allowance, and never run short mid-pour.
Cost per Square Foot Calculator
Sanity-check any remodel quote in seconds. Enter the cost and the area to get the per-square-foot figure and see whether it lands below, within, or above the typical range for that project type.
Deck Material Calculator
How much material to build a deck. Enter the deck size, board length, and joist spacing, and the tool returns deck boards, field joists, a footing-grid count, and screws — with the right waste factor built in. Field material only, so add your ledger, beams, stairs, and railing separately.
Fence Calculator
How much material to build a fence. Enter the total length and the tool returns posts, sections, rails, pickets or pre-built panels, concrete bags, and gate hardware — with picket spacing and a waste allowance handled for you.
Flooring Estimator
Calculate the number of flooring boxes to buy, including the waste factor for your install pattern, and total material plus labor cost.
Furniture Spacing Calculator
TV viewing distance, sofa-to-coffee-table gap, rug size, and walkway clearance — design-school rules made literal for your room.
Gutter Sizing Calculator
What size gutters and how many downspouts your roof needs. Enter the roof footprint, pitch, and your local rainfall intensity and the tool returns the recommended K-style gutter size (5 or 6 inch), the downspout count and size, and total gutter length — using the standard adjusted-square-footage method.
Home Affordability Calculator
How much house can you actually afford? This works backward from your income, debts, and down payment using the lender 28/36 DTI rules to the maximum home price you'd qualify for — the tool to run before you start shopping.
HVAC Sizing Tool
A quick cooling-load estimate based on square footage, climate, ceiling height, sun exposure, insulation, and occupancy.
Recessed Lighting Calculator
How many recessed lights a room needs for its use — with the total lumens and a suggested even spacing — so a room is neither cave-dark nor airport-bright. Enter the dimensions, the room use, and your fixture's lumen output.
Maintenance Scheduler
Build a 12-month home maintenance schedule in 30 seconds. Export to your calendar as .ics, save the URL to update it later.
Mortgage Calculator
Monthly payment with principal, interest, taxes, insurance, and PMI. The single number you actually need.
Mortgage Payoff Calculator
What does paying a little extra on your mortgage actually buy you? Enter your loan and an extra monthly principal payment to see the interest you save and the years you cut off the loan.
Moving Checklist
Generate an 8-week moving checklist tailored to your move size, distance, and whether you've got pets or school-age kids.
Mulch & Soil Calculator
Cubic yards and bags of mulch, topsoil, compost, or gravel for any garden bed. Enter the bed size and depth — or let the tool snap to the recommended depth per material — and see bulk versus bagged cost with the cheaper option flagged.
Paint Calculator
Estimate gallons of paint needed for any room, accounting for doors, windows, coats, and coverage.
Paver Patio Calculator
How much material to lay a paver patio. Enter the patio size and paver dimensions, and the tool returns pavers needed, base gravel and bedding sand in cubic yards, joint-sand bags, and edge restraint with stakes — waste included.
Refinance Break-Even Calculator
Should you refinance? Compare your current loan to a new rate and term to see the monthly savings, the month the closing costs break even, and the true lifetime impact — because a lower payment can still cost more.
Renovation Budget Estimator
Per-sqft baselines for common room remodels, with contingency built in. Get a realistic range before you call contractors.
Rent Affordability Calculator
How much rent fits your income, accounting for debts and a real savings target — not just the 30% rule.
Rent vs Buy Calculator
Renting isn't throwing money away and a mortgage isn't automatic wealth. Enter a home price, rent, and how long you'll stay, and this calculator compares the true cost of each — including interest, taxes, maintenance, the opportunity cost of your down payment, and the equity you'd build — to find the year buying breaks even.
Roof Shingle Calculator
How many shingles to roof a house. Enter the roof footprint and pitch and the tool returns the sloped area, squares, shingle bundles, underlayment rolls, starter, ridge cap, and drip edge — with waste built in. Enter the footprint, not the sloped measurement.
Room BTU Calculator
Size a single-room air conditioner, mini-split, or space heater. Enter the room dimensions, ceiling height, sun exposure, and occupancy, and the tool recommends a BTU load and the nearest common unit size to buy.
Room Planner
2D top-down room layout with drag-to-scale furniture. Save layouts to a sharable URL and hand the room dimensions straight to the Paint and Flooring tools.
Scope of Work Generator
Build a contractor-ready scope of work in minutes. Pick the work, add your rooms and an optional budget, and the tool generates a clean, printable brief — work items, exclusions, the questions to ask before signing, a rough timeline, and a budget range. Save it as a project to add material quantities from the calculators.
Siding Calculator
How much vinyl siding to clad a house. Enter the wall perimeter, height, and openings and the tool returns net wall area, squares, boxes, starter strip, J-channel, and corner posts — with the right waste factor built in.
Square Footage Calculator
Total area for a room, a floor, or the whole house. Add as many rectangular sections as you need — handles L-shapes and repeated identical rooms — and get the sum in square feet, square yards, and square meters.
Storage Planner
Plan shelving for a garage, closet, pantry, or basement before you buy a single unit. Turn how many bins and boxes you need to store into the number of shelf units, linear feet of shelving, and floor space they will occupy.
Tile Calculator
How many tiles for a floor, wall, or backsplash. Enter the area and your tile size, pick the layout pattern, and get the tile count, boxes to buy with the right waste factor, and a material plus labor cost estimate.
Trim & Baseboard Calculator
Linear feet of baseboard, crown, or chair rail for a room — and the number of stock lengths to buy, with corner waste and material cost included. Baseboard subtracts door openings; crown and chair rail run continuously.
Utility Cost Estimator
Plug in any appliance's wattage and usage. See daily, monthly, and yearly electricity cost at your local rate.
Wallpaper Calculator
How many rolls of wallpaper for your room — with the pattern-match waste built in. Enter the wall dimensions, roll size, and pattern repeat, and the tool nets out doors and windows to give you the exact roll count.
